DUMP-WAGON- Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed November 17,1905. Serial No. 287,867-

To all whom it may concern:

Be it known that I, HENRY C. TRIPP, of Auburn, in the county of Cayu a, in the State of New York, have invente new and useful Improvements in Dump-Wagons, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in dump-wagons of the class set forth in my Patent No. 756,912, issued A ril 12, 1904, in which a sin le chain is passe under one of the doors an connected to the other door for controlling the operation of said doors, which allows the chain to swing with the doors in close proximity to or across the discharged load, and therefore portions of i the chain necessarily drag through the load as the wagon is drawn forwardly. This causes the chain to be more or less clogged with mud or other sticky substance which may be conveyed in the wagon, and I have found that in cold weather this mud accumulates upon the chain to suchan extent as to interfere with its free operation. In my present invention I have sought to overcome this diflioulty by supporting the intermediate portion of the chain upon suitable sheaves at each end of the box, and instead of passing the chain under the doors it is extended forwardly through and along one side of the box some distance above the bottom from front to rear and has its front end attached to a vertical or upright winding drum at the right-hand side of the longitudinal center and at the front of the front end of the box, thereby bringing the greater portion of the chain wholly above the bottom of the doors. The dumping ground where the material conveyed by the wagon is usually discharged is generally very uneven, and it not infrequently happens that the open doors encounter obstructions while the wagon is bein drawn forward, thereby subjecting said doors to a severe strain and making it difiicult to draw the wagon forward.

One of the objects of my invention, therefore, is to provide means for elevating both doors simultaneously at the outer sides of the box, although the essential purpose is to control the operation of the doors by a single chain running from front to rear along the side of the box above the bottom.

A further object is to provide a vertical winding-drum for the chain with a ratchet and pawl operated manually, so as to obtain a rapid closing of the doorby a continuous revolution of the drum or by a series of forward and backward movements of the lever upon which the pawl is mounted.

A still further object is to provide the lever with means for locating the pawl out of action and to provide the drum with an additional ratchet and pawl, which latter may be thrown out of action by the foot of the driver, thus making it possible torelease the doors either by the manually-operated pawl or by the foot-pawl.

Another object is to arrange the sides of the box in downwardly-diverging planes, so as to permit the load to free itself more read ily on the discharge.

Other objects and uses will be brought out in the following description.

In the drawings, Figure 1 is a top plan of my improved dump-wagon and the various improvements used in connection therewith. Fig. 2 is a side elevation of-the parts seen in Fig. 1. Figs. 3 and 4 are respectively front and rear elevations, particularly in section, of the parts seen in Figs. 1 and 2. Fig. 5 is a transverse sectional view through the box, showing the bottom doors as drawn upwardly at the sides of the box.

In demonstrating the practicability of my invention I have shown a dump-box consisting of upwardly-converging sides 1, front and rear ends 2 and 3, and swinging bottom doors 1 4 and 4, which in this instance are normally disposed in a horizontal position when closed. The sides 1 are each provided with a series of, in this instance, three hinge-straps 5, having their lower ends lying in about the same plane as the lower edges of the sides and provided with hook-shaped bearings 6, which are open at the top to receive the hinge-pins 7 on the adjacent edges of the doors 4 and 4, said hinge-pins 7 being provided on the ends of suitable hinge-straps 7, which are secured to the bottoms of the doors in any wellknown manner, not necessary to further illustrate or describe. These side pieces 1 extend forwardly and rearwardly some distance beyond the front and rear ends 2 and 3, the forward extensions being provided with a suitable bolster 8 and cut-out 9, the latter being located between the bolster and front end'of the box to permit the wheels (not shown) to turn under the extensions and in front of the box proper, while the rear extensions are provided with a bolster 10 and a downwardlyv inclined ledge or shelf 11, the bolster 10 serviing to support the rear axle, (not shown,) and the shelf or ledge'l 1: serves as a bracebetween the sides and also allows any accumulation of dirt thereon to readily slide off,

The front extensions of the sides are braced against lateral. compression by upright transverse bars 12 and 13 and a seat-supporting bar 14, sufficient space being left between the as a chain 16, having one end attached to a vertical winding-drum 17- near the righthand side of the box and its rear end secured toan anchor18 on the same side of the box just outside of the rear end 3 and above the bottom doors and shelf 11 The lower end of the'drum 17 is-stepped in a suitable plate 19 on the bolster-bar 8- and is provided-with a ratchet-wheel 20, rigid thereon and engaged by a foot-pawl21. I A portion of this drum is journaled in the arms, as

22, of a U-shaped bracket 23, which is se' cured'tothe'adj acent side 1 of the box in front ofthe seat-support 14', said arms 22 being spaced some distance apart vertically to receive thewinding ofthe chain 16. A second ratchet-Wheel 24 issecuredtothe upper end of the drum directly above tlie-upperarm 22' and is normally engaged by detent 25 and hand p awl 26, the latter being mounted upon a hand-lever 27, which is loosely journaled upon the-upperend of the drum 17 directly abovethe ratchet-wheel 24.

The lever 27 is providedwitha link 28, whichisadapted to be hooked over the adj acent end of t-hepawl 26-to-hold said pawl in its inoperative position when it is desired to releasethe bottom doors to discharge the ment with their respectiveratchet-wheel 2O and-24:

If it is desired to release the doors, thehand-lever 27, with itspawl held out of operative-pos-ition by the-ring 28, may be swung around in the direction indicated by arrow X untilthebiting end of'the pawl26 engagesthe pawl 25- inside its pivot, thereby throwingiit out ofaction, whereupon the foot-p awl 21- may bekicked out of operative position,

thereby freeingthe drum and releasing the and extends rearwardly therefrom over a able sheaves 39 and having pendent ends which are attached to theopposite ends of its-corresponding door, as best seen in Fig. 2. load, it being-apparentthat the pawls or detent 2'1- and 25 are still in holding engage whichwill also release the 'drum 17 and allow the doors to open.

As previously stated, the front end of the cable or chain 16 is attached to the drum 17 swinging. idler 30 and then downwardly under the sheave 15 on the underlying door 4, thence upwardly over a suitable sheave 31 on the front end- 2 of the box, thence downwardly under the sheave 15 on the front end of 7 5 the door 4, thence upwardly over one or more sheaves 32 on or nearthe front end or side ofthe box, said cable passing through the front extension of theadjacent side, and thence rearwardly along; said side through a sheave 33 in an opening in the rear'extension of the box, after which it passes downwardly under the sheave 15 on the rear'end of the door 4, thence upwardly overa sheave 34 on the rear end of the box and downwardly under the sheave 15 on the rear end of the door 4 and has its rear end attached to the anchor 18 on the same side of the-box near which the drum 17 is located. It therefore follows that the front and rear ends of the chain or cable draw transverely at the front and rear ends-ofthe box, while the intermediate portion ofsaid cable travels along and in close proximity to the outer face of one side of the box opposite-to that near'which the-ends ofthe cable are attached. By this arrangement the greater portion-of the cable isalways out of the way of theload-and is-less liable toaccumulate-mud or other material which might interfere withits-operation. I

The'means for raising the doors upwardly at the outersid'es of the boxisshown= as consistingof the rock-shaft 35', which is journaledi in the-front extensionsof the sidesl infront of the transverse bar 13 and provided with upwardly --projecting arms 36 and 37, to which are attached the front ends of opposite cables 38 at the outer-sides of the box, oneforeach door, eachcable renderingover'suit- One of the arms 36, preferably that at the left side of the box, is extended upwardly some distance for forming ahandpiece 41-, 115 .which is within convenient reaching distance' ofthe seat, and when it is desired to raise the door after the load hasbeen dis charged therefrom the lever 4 1 is thrown for lwardly and may be engaged with suitable 12o shoulders or detents 42, as best seen inFigs. 1

j and 2, for holding the doors in their elevated position, as seen in Fig. 5. not only draws the doors upwardly clear'of the discharged load, but also causes the inner I 25 facesof the doorstoscrape against the lower edges of the sides of the box, thereby remov- Iing any dirt which mayadhere to: the doors, the latter being guided intheir verticalmovement betweenflanged rollers 44;.which'arese- 1 30 This operation IOC cured to and project outwardly from the opposite sides of the box and serve to register the hinge-pins 7 with the open sides of their respective bearings 6, when the doors are allowed to drop by the disengagement of the le ver 41 with the detents 42.
